NON-REFILLABLE BOTTLE.

Specification of Letters Patent.

Patented Dec. 19, 1905.

Application filed May 25,1905. Serial No. 262,222.

To all whom it may concern.-

Be it known that I, FRANoIs S. HEFFER- NAN, a citizen of the United States, residing at Springfield, in the county of Greene and State of Missouri, have invented certain new and useful Improvements in Non-Refillable Bottles, of which the following is a specification.

This invention comprises improvements in non-refillable bottles, the details of which will be pointed out in the following specification, taken in connection with the accompanying drawings, in which Figure 1 is a vertical section through a bottle-neck having my improvements applied thereto. Fig. 2 is a similar view, the parts being inverted; and Fig. 3 is a section on the line 3 3 of Fig. 1, the valve C being omitted.

Referring to the drawings, A indicates the neck of a bottle, B the valve-casing within the bottle-neck, and C and D indicate valves arranged in the upper and lower compartments, respectively, of the valve-casing. The valve-casing comprises two similar semicylindrical parts I) b, Fig. 3, one of said parts being shown in elevation in Figs. 1 and 2. The casing is made in two parts in order that the valves C and D may be readily inserted therein. After the valves are in place the two, halves of the casing are cemented together and inserted in the bottle-neck, in which the complete casing is secured by suitable cementing material, such as silicate of soda. The czlising and valves are preferably made of g ass.

As shown, the casing has a central partition 1, dividing it into an upper or outer compartment b and a lower or inner compartment b and it also has a partition 2 at its inner or lower end. The central partition has a cylindrical socket 3 at its center and a port 4 extending through the base of the socket. The partition 2 has a similar socket 5 and a port 6 in the base of said latter socket. Each half of the casing has longitudinallyeXtending guide-ribs 7 projecting radially inward from the wall of the casing to the peripheries of the cylindrical sockets in both compartments. Stops 8 and 8 for thevalves are arranged near the upper ends of both compartments, these stops, as shown, being upon the inner faces or edges of the guideribs. T

The valve C in the upper compartment, as shown, consists of a cylindrical cup, preferably of glass, having its closed end adapted to fit over the port 4 and its open end toward the mouth of the bottle. This valve is arranged to fit closely within the socket 3 and to move longitudinally of the casing between the guide-ribs when the bottle is inverted. The lower or inner valve D similarly consists of a cylindrical cup adapted to fit into the socket 5 and close the port 6. Within this valve D is fitted a piece of cork cl or other suitable light material, which will cause the valve D to float when the compartment 1) is filled with liquid.

In operation when the bottle is in the upright .position (shown in Fig. 1) both valves will remain upon their seats. If it is attempted to pour .liquid into the bottle in its upright position, the liquid will enter the up per valve C and simply serve to hold thelatter more firmly against its seat in the socket 3. N0 liquid can therefore be poured into the bottle in its upright position. When the bottle is inverted to pour out its contents, the valves will drop away from their seats and rest against the stops 8 and 8 as shown in full lines in Fig. 2. The li uid can then pass through the port 6 aroun the valve D, which is held away from the port 4 by the stops 8, thence through the port 4, and out past the valve 0. If it is attempted to siphon liquid into the bottle when the latter is inverted while the valve C will remain against the stops 8, the valve D will float upward as the liquid enters the compartment b and said valve will be carried into the socket 5 and close the port 6, and thus prevent the ingress of liquid. The cork or float (1 being inclosed within the cylindrical valve D does not come in contact with the guide-ribs, and there is no danger of the valve being hindered or stopped in its movements by the swelling or enlargement of the float when the latter becomes moistened or saturated.

Having described my invention, what I claim, and desire to secure by Letters Patent of the United States, is-

1. In a non-refillable bottle, the combination with the bottle, of a tubular valve-casing fitting within the bottle-neck, said casing having a central partition dividing the casing into upper and lower compartments, and a lower partition, each partition having a port therethrough, and said casing having longitudinally-extending guide-ribs projecting inwardly from its wall toward said ports, and having stops near the upper ends of said compartments, a cup-shaped valve in said up- IIO per compartment, having its open end toward the mouth of the bottle, a similar valve, similarly arranged in the lower compartment, and a cork or float fitting within said latter valve.

2. In a non-refillable bottle, the combination with the bottle, of a tubular valve casing fitting within the bottleneok, said casing having a'central partition dividing the easing into upper and lower compartments, and a lower partition, each partition having a central socket therein and a port extending through the base of the socket, and said casing having longitudinally-extending guide-ribs in line with the walls of said sockets and stops
